Fleas are a common parasite of dogs and cats. They live on the pet and feed on blood meals. Fleas go through four life stages - egg, larva, pupa, and adult. Many owners are surprised to learn that fleas are often picked up from within the home, not just from other animals outside. Pets need to be treated with products like Fiprospot that kill fleas, and the home environment needs treating with products like Acclaim that kill all life stages of fleas, to achieve comprehensive flea control. Proper flea treatment of pets and homes is important all year round.
